AI Technical Summary

Technical Problem

The production process of existing low-altitude aircraft transparent parts is complex, time-consuming, low efficiency, and high cost, making it difficult to meet the requirements of scratch resistance and weather resistance.

Method used

The process of integral molding of the substrate body, the UR layer and the composite diaphragm layer in the mold is adopted. The composite diaphragm layer is formed on the inner side of the substrate body and the PUR layer is formed on the outer surface. The performance of the transparent parts is improved through in-film reaction molding and hardening coating.

Benefits of technology

It greatly reduces production costs and time, improves the production efficiency and qualification rate of the product, improves the toughness, heat resistance, scratch resistance and weather resistance of transparent parts, and can meet the requirements of bird collision experiments.

Abstract

The utility model belongs to the technical field of aerocar parts, and provides a low-altitude aircraft transparent part which comprises a base material body, a PUR layer and a composite membrane layer, the base material body, the PUR layer and the composite membrane layer are integrally formed in a mold, and the composite membrane layer is formed on the inner side face of the base material body in the mold. The PUR layer is formed on the outer surface of the substrate body in the mold. The base material has the advantages that the toughness and the heat resistance of the base material body are greatly improved, and the bird strike experiment can be effectively met; through reaction molding in the film, the composite film sheet or the hardened coating can effectively improve the scratch resistance and the weather resistance; the composite membrane and the in-membrane forming can be formed in one step on a mold in the process, the production process is shortened and optimized, the production cost is greatly reduced, and the production efficiency and qualification of products can be improved.
